Baker 7th grade science 2003-2004
Earth, Inside & Out
The Earth is divided into three layers
1. Crust 2. Mantle3. Core
Today we are going to learn about the center or core of the planet
http://www.iteachbio.com/Earth_Science/Earth_Science/The%20Core-.mov
Baker 7th grade science 2003-2004
Core
i) Deep within the Earth is the core
ii) The core is made mostly of nickel & iron
iii) Twice as dense as the mantle.
Main source of heat that triggers the convection currents
Baker 7th grade science 2003-2004
The core is made of two layers
(1) Outer core: Liquid & is responsible for the Earth’s magnetic field.
Inner core: solid
Today we are going to learn another layer of the planet the Mantle
http://www.iteachbio.com/Earth_Science/Earth_Science/The%20Mantle-.mov
Baker 7th grade science 2003-2004
Mantle
(1) Hotter and denser than the crust because the deeper you go inside the earth, the temperature & pressure increases.
(2) Made of solid rock.
The Mantle is made of two zones
Baker 7th grade science 2003-2004
Mantle Zones (a) Lithosphere (i) Thin, uppermost
part of the mantle; cooler & less rigid
(ii) Floats on the athenosphere, and slides around very slowly.
(iii) The upper part of the lithosphere melts rocks, forming a substance called magma.
Baker 7th grade science 2003-2004
Magma
1. Magma (melted rock) moves like hot oatmeal.
Uneven heating causes material in the mantle to constantly and slowly rise & fall in convection currents.
Convection Current: process by which hot fluid rises to the surface, and then sinks again, like soup being heated in a saucepan
Baker 7th grade science 2003-2004
(a) Asthenosphere
Hot, weak zone directly under the lithosphere
Flows at a very slow rate
Today we are going to learn about the last layer of the Earth, the Crust
http://www.iteachbio.com/Earth_Science/Earth_Science/The%20Crust-.mov
Baker 7th grade science 2003-2004
Crust (1) This is the outermost
layer of the Earth. (2) This is the layer we walk
on. (3) It is a thick, rocky skin. (4) If we think of the Earth as
a billiard ball, this crust is as thin as a postage stamp stuck on a billiard ball.
(5) At its thickest, which is under mountain ranges, the crust is only about 35km (22mi) thick.
Baker 7th grade science 2003-2004
And what type of crust would you like with your Earth?
There are two types of crust
Baker 7th grade science 2003-2004
Continental Crust:
1. Makes up the continents
2. Contains light colored rocks such as granite.
3. Floats high on the mantle
Baker 7th grade science 2003-2004
Oceanic Crust
1. Makes up the ocean floor
2. Contains the dense rocks such as basalt
Thinner than the continental crust
